Over 90% of the positive infections came from a single test provider; three-quarters of the positive tests were from people who reported no symptoms; the positive results were widely scattered across various groups in our population, with only one potential cluster that seemed more likely to be associated with their proximity to a particular testing location; and over 90% of the reported infections were for people who were fully vaccinated.
We then reviewed the detailed data and noted some very unusual patterns in the results that suggested there was a possible issue with a testing provider rather than a broader campus outbreak. When we consulted with that provider, we learned that they had begun using a different protocol than they had previously used at Rice, resulting in significant differences in how test results are decided. This change in testing protocol had not been disclosed to Rice. We asked that they immediately revert to their prior testing protocol and they have done so.
